SHUTTLE.

Specification of Letters Patent No; 10,335, dated December 20, 1853.

Similar letters in both the figures refer to like parts.

The nature of my invention relates to the" method of preventing the thread from looping when it pays off too tast from the bobbin. f

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawthe body A, of the Shuttle is Similar in form to the ordinary shuttle, except that the bottom is entirely closed.

B, is the bobbin upon which the yarn is wound, and Vis held in the shuttle by the spindle O, and spring catch D. In front of the point of the bobbin is a hinged guard piece E, the lower part F, of which rests against a spring G, so as to hold the guard piece open or shut as may be desired for placing or shielding the point of the bobbin.

The thread a from the bobbin passes through a hole b, in the guard plate and thence through a ring H, and under a spring brake to give it even tension.

It is well known that at times the thread or yarn pays off too fast from the bobbin, and the rapid ino-vement of the shuttle throws out the slack of the thread and yarn and causes looping` or tying over the shuttle, which sometimes provesr destructive to the web. It is to avoid this diiiiculty that I have devised the guard plate.

I am aware that a pin or pins have been permanently arranged across the box of the shuttle for preventing this evil, and also that, a slide has been used, but both these were, and of necessity had to be, placed in front ot the point of the bobbin, so that the bobbin could swing into and out ot' Vthe box.'

But neither of these devices overcomes the diiiculty of looping with any degree of certainty. Y

The hinge of my cap or guard E, is in front of the point of the bobbin, but the guard itself extends back o ver the point of the bobbin, las seen in the drawing to prevent entirely the thread or yarn which must pass oli" from the pointof the bobbin, from getting back far enough, to throw out from the shuttle, and by this means I entirely over'- come the evil.

I would state that` a closed shuttle has been used for running cloth where a cap instead of a bobbin is employed; this I do not claim, but l to secure by Letters Patent is,

In combination with the bobbin of an ordinary shuttle, the hinged guard, projecting from and overvthe point toward the heel of the bobbin, for the purpose of preventing the thread or yarn when paying ofi-' too fast,

from looping or tying substantially as described. f Y y DAVID CARROLL. IVitnesses A. B. S'roUGH'roN, T. C. DUNN.V
